Agriculture & Bulk Storage Overfill Alarm Systems

Agricultural operations often store liquids such as fertilizers, chemicals, and fuel in aboveground tanks, where overfills or leaks can lead to costly damage, environmental hazards, or operational disruption. The Meco AST Overfill Alarm provides a dependable audible alert when liquid levels reach a preset point, helping farm and agribusiness operators prevent overfill incidents and maintain safe storage practices.

Meco alarms are designed for use in remote, high-use, or outdoor storage tanks, making them ideal for agricultural applications that demand durability and low-maintenance operation.

Agricultural storage environments can be harsh, with extreme temperatures, dust, and intermittent monitoring. The Meco AST Overfill Alarm is a battery-operated, intrinsically safe audible alarm designed for these conditions, alerting operators promptly when tanks are approaching capacity.

When the preset alarm level is reached, a 100 dB pulsating audible signal notifies personnel, allowing immediate intervention to prevent spills or overflow events.

Overfills in farm or bulk storage tanks can damage crops, contaminate soil, or compromise safety. The Meco AST Overfill Alarm assists in overfill prevention by providing a clear and immediate warning during tank filling or transfer operations.

Key features for agriculture applications:

• Adjustable float switch to set alarm points based on tank requirements
• Push-button test before filling to verify alarm functionality
• Manual reset after alarm activation
• Suitable for both standard and protected aboveground tanks

These features help agricultural operators maintain safe, efficient, and repeatable tank management practices.

Farm and chemical storage tanks often require equipment that meets safety standards for hazardous liquids. The Meco AST Overfill Alarm is Certified Intrinsically Safe to ANSI/UL 913, allowing use in locations with flammable or reactive agricultural liquids.

Standards compliance includes:

• NFPA 30A
• UL 2244
• UFC requirements

This ensures alarm systems support regulatory compliance and operational safety for agricultural storage.

Many agricultural tanks are in remote locations without easy access to line power. The Meco AST Overfill Alarm operates on 9-volt battery power or an optional 12-volt intrinsically safe line power, providing flexibility for diverse farm layouts.

• 9 V battery operation with ultra-low power draw
• Optional 12 V wiring for continuous power where available
• Minimal maintenance and long service life

Note: For compliance in certain Canadian regions, alarms must be wired and powered by a 12 V source. Always verify local regulations before installation.

For double-wall tanks or secondary containment systems, the Meco alarm can be configured as an interstitial leak monitor. Probe lengths can be custom-built to match tank manufacturer specifications, providing additional protection against leaks and environmental impact. 

Agricultural tanks often face extreme weather conditions, from sub-freezing winter temperatures to hot summer days. The Meco AST Overfill Alarm is designed for long-term performance in these environments.

Operating temperature ranges:

• 9 V Alkaline: −4°F to +130°F
• 9 V Lithium: −40°F to +158°F (recommended for extended life)

With no power draw during normal operation, the alarm offers years of reliable service with minimal maintenance.

Meco AST Overfill Alarms are used across a wide range of agricultural and bulk storage applications, including:

• Fertilizer and chemical storage tanks
• Fuel storage for farm equipment
• Irrigation or liquid feed storage tanks
• Remote storage sites requiring low-maintenance monitoring
• Bulk liquid storage operations in agribusiness

These alarms provide immediate, actionable alerts to protect operations, crops, and personnel.

Whether you need a single alarm or multiple units for multiple storage tanks, our team can help select the right configuration for your agricultural or bulk storage application.
